4ing drawings, and to letters or gures of reference marked thereon,which form a part of this specification.

This invention relates to improvements in i ink fountains for printingpresses, and more particularly job presses.

It has been found dii'icult to regulate the supply of ink to the feedroll, and to conveniently clean the latter, owing to the fact thatheretofore the bearings of the feed roll were stationary, or the bottomof the fountain was adjustable.

According to my invention, I arrange the feed roll so that it maybeswung on its bearings vaway from the mouth of the fountain, and alsoprovide a detachable connection between the swinging frame carrying theroller and an eccentricy shaft, whereby when the roller is in normalposition, and the connection is made, the space for the egress of theink may beregulated.

Therefore, the object of the invention is to provide means forregulating the supply of ink to the feed rollerand to provide meanswhereby the feed roller may be `detached from the regula-ting means andthrown upwardly and away from the fountain forrepairs or cleaning.

The inventionV also` relates to the specific details of construction andarrangement of parts which will be hereinafter described, andparticularly pointed out in the claims.

In the drawings :.Figure 1 is a perspective viewof my improved fountain.Fig. 2 is a vertical central section of the sam-e. Fig. 3 is a planview. Fig. 4 is a side elevation, the detachable connection beingdisengaged and the ink roll thrown up. Fig. 5 is a detail view of theeccentric shaft for adjusting the feed roller.

pawl out of operative position.

1 indicates a fountain, comprising an inclined bottom 2, and sides 2a,each of which is curved at its forward end tov form a seat for theinking roll, when the latter is in operative position, and above thecurved portionsv are perforations 4. An ink roll 5, is located in theforward end of the fountain, its shaft 6, being mounted in bearings independing arms 7 pivotally supported on screws 8, passing through theopenings 4, in the sides 2a.

On one end of the shaft 6, is rigidly secured a ratchet wheel 9, whichis embraced by the bifurcated arms 10, of an operating lever 11. Mountedin the operating lever is a spring pressed pawl 12, provided with aprojection 13, with which a locking dog 14, may engage if it be desiredto hold the By this construction, if it be foundnecessary t0 discontinuethe feeding of ink from the fountain, the locking dog may be engagedwith the pin which will hold the pawl out of contact with the ratchetwheel. It will of course be understood that even though the pawl isdisengaged from the ratchet wheel,

the lever may continue to be operated by the usual connections (notshown). The roll 5, is formed at its ends with flanges 17, to form asnug lit in the curved ends of the sides 2a, which prevents the inkoozing out at the end of the fountain. f Each of the arms 7, is providedwith av pair of ears 18, and a pin 19, supported in said ears, toprovide a means for coupling the detachable means, now to be described.A shaft 20, is mounted in bearings inthe rear of the sides 2a, and underthe bottom 2. Near the ends of this shaft are eccentrics 21, which fitin openings 22, in detachable side bars 23, the latter having notches 24at their forward ends to fit over the pins 19, and between the ears 18.Nuts and washers 25, are fitted over the ends of the shaft 20, to holdthe detachable bars 23 in position on the eccentrics. An adjusting lever26, is secured to the shaft 20, near one end, and it is formed with acurved slot 27, through which passes a screw 28, engaged by a bindingnut 29, which binds the adjusting lever against the side of the fountainto hold the In operation, the fountain is clamped to the press by thesupport and screw 30, and the roll 5, is thrown down on the pivots 8',to engage in the curved seats of the fountain.

a rIhen the detachable connecting bars 28, are

fitted between the ears 18 .and the notches 2a engage over the pins 19.The adjusting lever 26, is now moved, forward or backward, as the casemay be which turns the shaft 20, hence by reason of the eccentrics 21,the roll 5, through the medium of the bars 23, is adjusted toward orfrom the forward end of the inclined bottom, and the ink passage isregulated. This adjustment having been completed, the set screw 29, isscrewed up against the lever 26, and holds the parts in position. Now ifafter operating the press for a while it be found that the ink flows toofreely, or is sluggish, the set screw 29 is released and the adjustinglever is turned accordingly, and the ink passage is regulated.

Vhen desiring to clean the roll 5, the bars 23, are raised to disengagethe notches 24, from the pins 19, which frees the arms 7*7, and thelatter may then be swung upwardly above the fountain 1, as shown in Fig.4;. When the roll is in this position, it may be conveniently cleaned,and swung again in its operative position, and the connecting barlowered, when t-he fountain is in condition for further operation.

A fountain constructed according to` my invention is extremely simple,and will save considerable time in cleaning the roll and affords aconvenient means for regulatingv the flow of ink without stopping thepress.

Having thus described my invention, what I claim is:

1. In an ink fountain, the combination with a stationary inclinedbottom, a swinging frame pivotally supported at the end of the fountain,a roll mounted in the swinging frame, detachable elements engaging theframe to hold the roll adjacent the end of the inclined bottom, meansincluding a cam engaging the detachable elements for moving the lattertoward or from the end of the fountain to position the roll withreference to the end of the inclined bottom to regulate the passage ofink, and a handle for revolving the cam.

2. In combination, an ink fo-untain formed with curved end portions, apivotally mounted roll supported on the fountain and provided with endflanges which fit in the curved end portions, and means for adjustingthe roll to regulate the passage of ink, said means including eccentricsand connecting bars.

3. In combination, an ink fountain comprising sides having curved endsand a bottom, a pair of hangersv pivoted tothe sides, a roll mounted inthe hangers and fitting in the curved portions of the sides, means forintermittently moving the roll, eccentrics mounted on the fountain, barsconnecting the eccentrics and the hangers, and an operating device formoving the eccentrics to adjust the position of the roll with referenceto the end of the bottom.

4L. In` combination, a fountain comprising sides and a. bottom, a pairof hangers pivotally mounted on the fountain, a roll mounted in thehangers, a pair of detachable side bars connected to the hangers, andmeans for moving the side bars toward or from the end of the fountain.
